Vardenafil is used for: Treating erectile dysfunction (ED). It may also be used for other conditions as determined by your doctor. Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by helping to increase blood flow into the penis during sexual stimulation. This helps you to achieve and maintain an erection

Who we are

Attotech Handelsbolag was created by Erik Mansten (former Gustafsson) and
Thierry Ruchon in november 2006.
The founders were both working in the
attosecond science group led by Anne L'Huillier,
located in the
department of Atomic Physics at Lund University.
Attotech collaborates with a local company that manufactures the main hard parts of the product.
The proximity of this workshop and the small size of Attotech makes easy to build a product that
in an excellent manner fits your needs. Attotech is open to discussions to custom-make any
pulsed valve.

History of Attotech's high rep-rate pulse valve

The rep-rate of the intense lasers used in high field physics reaches nowadays the kHz regime.
The device that may limit the counting statistics in this field often becomes the frequency of the injection of gas
in the vacuum chambers. For instance, for using a velocity map imaging spectrometer (VMIS) one may appreciate being
able to collect data at a kHz rate, which imposes using a gas valve at the kHz rate. By the same token, if one uses a
kHz laser to shoot at a gas target, the density of atoms reachable is often limited by the amount of gas that can be
pumped away. Using a kHz target that is only open one tenth of the time, one access ten times higher densities.
This last example is the one that drove us to develop the Attotech pulse valve. It has been tested in our attosecond
setup over the past year, and allowed us
to obtain trains of attosecond pulses in a new wavelength range (around 80 eV), with an unprecedented short
duration (130 as).
The products we propose are either copies
of the one we used in this experiment, or custom made ones to fit in a specific setup.
